Rajeesh Menoth · Answer

Hi, What is difference between For loop and Foreach loop in C#.Net For Loop: In case of for the variable of the loop is always be int only. The For Loop executes the statement or block of statements repeatedly until specified expression evaluates to false. There is need to specify the loop bounds(Minimum, Maximum). example: using sytem; class class1 { static void Main() { int j=0; for(int i=0; i { j=j+1; } Console.ReadLine(); } } Foreach loop : In case of Foreach the variable of the loop while be same as the type of values under the array. The Foreach statement repeats a group of embedded statements for each element in an array or an object collection. You do not need to specify the loop bounds minimum or maximum. example: using sytem; class class1 { static void Main() { int j=0; int[] arr=new int[]{0,3,5,2,55,34,643,42,23}; foreach(int i in arr) { j=j+1; } Console.ReadLine(); } } Reference : http://sachin-csharp.blogspot.in/2012/01/what-is-difference-between-for-loop-and.html

a for loop is a construct that says "perform this operation n. times". a foreach loop is a construct that says "perform this operation against each value/object in this IEnumerable" https://msdn.microsoft.com/en-us/library/ttw7t8t6.aspx OR http://www.onlinebuff.com/article_difference-between-for-loop-and-for-each-loop-in-csharp_1.html I hope this will help you.

http://www.dotnetperls.com/foreach Foreach. A program iterates over a collection. The index of each element is not needed. Only the elements are needed. With foreach we access just the elements. http://www.dotnetperls.com/for For-loops. Often we loop through numbers. These can be used as indexes of an array, or just for a numeric algorithm. For-loops are ideal here.
